Answer:
P = [tex]P_{atm} + \rho \ g \ h[/tex]
Explanation:
For this exercise we use that the pressure at a given level is the same, so we set a level on both sides of the pressure gauge, just the point where the liquid is on the system side, with a pressure (P)
P = [tex]P_{atm} + \rho \ g \ h[/tex]
where [tex]P_{atm}[/tex] is the atmospheric pressure in pascals, ρ the density of the liquid, g is related to gravity and h the height of the liquid from the marked reference.
